“…In these, the PZT harvester is placed in a fluid flow for energy harvesting, it undergoes limit cycle oscillations (LCOs) that can be converted to output electrical energy to operate electronic devices or for storage [108]. In the fields of aerospace and civil engineering, when the structure is subjected to fluid flow [109,110], it may undergo the phenomenon of bifurcations [111][112][113], LCO [114][115][116], internal resonance [117,118], and disorder motion [119,120]. In mega structures, aerodynamic phenomena such as vortex-induced vibrations (VIVs) [121], flutter [106,122], and galloping [123] may result in excessive vibrations that can damage or even destroy the structures [124].…”

From last few decades, piezoelectric materials have played a vital role as a mechanism of energy harvesting, as they have the tendency to absorb energy from the environment and transform it to electrical energy that can be used to drive electronic devices directly or indirectly. The power of electronic circuits has been cut down to nano or micro watts, which leads towards the development of self-designed piezoelectric transducers that can overcome power generation problems and can be self-powered. Moreover, piezoelectric energy harvesters (PEHs) can reduce the need for batteries, resulting in optimization of the weight of structures. These mechanisms are of great interest for many researchers, as piezoelectric transducers are capable of generating electric voltage in response to thermal, electrical, mechanical and electromagnetic input. In this review paper, Fluid Structure Interaction-based, human-based, and vibration-based energy harvesting mechanisms were studied. Moreover, qualitative and quantitative analysis of existing PEH mechanisms has been carried out.
